Hang in there Betty. I teach in a small town (in which I did not grow up,
and I don't currently live) where "you have to know somebody" to get in . .
I didn't know anybody! For years I was asked basically who are you? and
who did you know? I was hired because of good grades, a BFA (so I had more
credits in studio areas which gave me an edge for specialized h.s.
positions), and experience teaching kids in camps, etc. Plus, keep in mind,
jobs come up out of the blue. Administrators have to act fast, by the time
jobs are posted, they may already have interviews set up from their files.
I had my resume on file at all schools within a two hour radius from my home
and kept them updated until I got my full-time job. I didn't day to day
sub, but I took any long term sub position I could get. It took me four
years to get full-time employment.
